Question

ons in Part A List a possible set of four quantum numbers in,.m, m) in order for the highest energy electron in galium, Ga. Refer to the periodic table as necessary. Enter four numbers separated by commas (e.g. 3,2,-2,1/2). View Available Hint(s) Submit

Answer 1

looks like this Electronic Configuration of gallium a. [Ar]3d" 482 48' found in gallium is located in | Highest - energy electron a tp-orbitale principal Shell, and quantum number n election present will be 4 because n denotes in 4th Shell. So, n=4. Angular momentum quantum number, & the subshell in which the election which describes resides 6ے بل فلسطكله- كلاد ol= ol=2 l=3 the p -subshell the d - subshell the f-subshell in the p-subskell, it follows that Sincy election is located its value is 1. exactly in which The magnetic quantum number , me, tells I orbitul an electron can expect to find 1 for I can p -subshell, d=1, the magnetic quantum number take the values ome = -1 → the Ph orbital o me = o the py orbital ome = the pe abital

Since the p-subshell only place it in the first Po for which m = -1 contains available are eledion, we can p-orbital, which is finally, the spin quantum number, my, can only take one of two possible values o mga t a spin-down electron o my = +1 a spin-up electron Since the orbital Contains are electron, it follows that it I Could be either spin-up or spin-down , so we get two possible sets of quantum number n = 4 6=1 me = -1 → mg = -1 n=4 → 1=1 m = -1 → my=+1 Amen , l, me ms 4 , 1,-1, or n, l, me my 4, 1, 1, the Page No.
